16.4.3
Group single mode is selected when A/D conversion is to be performed on a number of channels.
A/D conversion is started when the ADST bit is set to 1, according to the specified conversion
start condition. The ADST bit remains set to 1 during A/D conversion, and is automatically
cleared to 0 when conversion ends for all the specified input channels.
On completion of conversion for all the specified input channels the ADF flag is set to 1. If the
ADIE bit is set to 1 at this time, an ADI interrupt request is generated. The ADF flag is cleared by
writing 0 after reading ADCSR. (It can be cleared with the BCLR instruction.)
Figure 16.5 shows an example of A/D converter operation when AN
